Recently, a netizen captured a tweet of Kim Jae Joong’s mother, Oh Seo Jin, and posted it on an online community board with the title “Kim Jae Joong’s sister about to debut.”

In the posting, Oh wrote, “The youngest one decided to enter the Department of Theater and is about to debut. We’ve met director yesterday, and today we’re going to have a meal with station manager at an annex hall of KBS building. He says that he likes her pure image, but since she doesn’t know how to dress up in a stylish way, she seems to fall behind the trend. I’m so concerned.”

Along the posting, a picture of Kim Jae Joong’s sister was revealed. It was first uploaded on February 4 by Oh on Twitter. Kim’s younger sister shows well-defined features just like her brother, and her flawless skin appeals an innocent image.

Netizens reacted: “No wonder they are related by blood.” “Is this another brother and sister celebrities after Kim Tae Hee and Lee Wan?” “She’s a pure beauty.”
